Abstract
The utility model discloses a corrosion resistant riveted structure of connected pieces of different metals, which comprises the connected pieces of different metal materials, wherein, each connected piece is provided with a riveted hole; a septum is arranged between contact surfaces of the connected pieces; a non-metal lining is arranged in the riveted hole of the connected piece, and rivets are arranged in the non-metal lining to connect the connected pieces of different metal materials. The contact surfaces of the connected pieces of different metal materials are separated by the riveted structure, that is to say two materials are not directly contacted when different metals are connected, thus the problem that electrochemical corrosion is easy to produce because electrochemical properties of two materials are different is solved, and the production of the electrochemical corrosion can be effectively reduced and the reliability of connection is increased. The utility model not only can be used for a connecting structure in bodywork technics, but also can be used for other connecting parts.
Description
Technical field
The utility model belongs to the linkage structure in the vehicle body technology, is specifically related to corrosion resistance structure between the connected piece of different metal materials.
Background technique
In vehicle body structure, generally adopt full steel structure or all-aluminium construction, corrosion resistance solves easily.When steel aluminium mix to connect, particularly during the riveted joint between the steel aluminium, because the difference of the electrochemical properties between steel aluminium easily produces electrochemical corrosion, influence appearance quality, the reduction join strength.Have not yet to see the relevant document that solves above-mentioned that problem.
Summary of the invention
The purpose of this utility model is to provide a kind of riveted structure of corrosion resistant different metal connected piece, to address the above problem.
The technical solution of the utility model is: the riveted structure of corrosion resistant different metal connected piece, it comprises the connected piece of different metal materials, connected piece is established riveted holes, establish barrier film between the surface of contact of connected piece, establish non-metallic bushings in the riveted holes of connected piece, establish the connected piece connection of rivet in the non-metallic bushings different metal materials.
This structure separates the surface of contact of the connected piece of different metal materials, be that different metal is when connecting, two kinds of not directly contacts of material, solved like this because the electrochemical performance difference of two kinds of materials, easily produce the problem of electrochemical corrosion, can reduce the generation of electrochemical corrosion effectively, improve the reliability that connects.It not only can be used for the linkage structure of vehicle body technology, also can be used for other connected element.
Description of drawings
The riveted structure schematic representation of the corrosion resistant different metal connected piece of accompanying drawing
Embodiment
As shown in drawings, all offer riveted holes 6,7 on the connected piece 1 of steel material and the connected piece 5 of aluminum material, establish non-metallic bushings 3 in the riveted holes 6,7, non-metallic bushings 3 is a T-shape, adoptable material such as PP, PE etc.Establish barrier film 2 between the surface of contact of connected piece 1,5, barrier film 2 is the diaphragm that sealer or Bond form.Overlay film 8 is established in the end of two connected pieces 1,5, and promptly two connected pieces 1,5 are covered by overlay film 8.Barrier film 2 and overlay film 8 are the diaphragm of sealer or Bond formation.The non-metallic bushings 3 that rivet 4 passes in the riveted holes 6,7 is connected the connected piece 1 of steel material with connected piece 5 rivet clasps of aluminum material, the flanged surface of non-metallic bushings 3 is greater than the surface of contact of rivet head, and length is identical with riveted holes.Rivet 4 adopts the steel rivet.
Compare aluminium matter rivet, the steel rivet can improve join strength on the one hand, can avoid occurring the corrosion-resistant situation that is unfavorable for of the little positive plate/big negative electrode of aluminium matter rivet on the other hand.Non-metallic bushings and sealer (or binder) are kept apart steel and aluminium fully, and blocking-up electrochemical corrosion circuit effectively reduce the generation of electrochemical corrosion, so this is a kind of typical anti-corrosive properties structure.
